Ran the Carfax per your recommendation, Klaus. Thanks for that, I never would have thought of it, otherwise.

Turns out the car has had 3 owners before me. The last one bought it in 2012 with 86k on the clock and it has 169k now. Up until 86k I can track all the dealer service it had but once the last owner bought it it vanished from the radar. I'm assuming she had an independent garage service it, so I have no idea when the timing belt was done. Rather than roll the dice, I'm just going to do the timing belt and ancillaries along with the water pump at 200k and keep track from there.

I know where the previous owner lived by doing an internet search and she's about 10 miles up the road from me. I'll take a drive out there to her last known address and see if she'll talk to me about the car. If I can get the independent garage to part with the service history I'll be in like Flint...8)
